Abstract: Position/orientation information that indicates the position and orientation of an image sensing device is estimated on the basis of three-dimensional position information of a registered feature and a feature in a frame image captured by the image sensing device. Three-dimensional position information of an unregistered feature is generated on the basis of the estimated position/orientation information, and the generated three-dimensional position information is registered. The generation and registration of the three-dimensional position information of the unregistered feature are controlled in accordance with execution of the estimation.

Abstract: Compatible video signal information having first information indicating a pixel number of a video signal displayable by a video display apparatus and second information that is setting information required in order for the video display apparatus to display a video signal having the pixel number is transmitted to a video output apparatus. In the case where a video signal received from the video output apparatus after the compatible video signal information is transmitted is a video signal having a pixel number displayable by the video display apparatus but not being displayable, the compatible video signal information is updated so that setting information for the pixel number of that video signal is included in the second information.

Abstract: An image processing apparatus generates, for an image, partial histograms by dividing a luminance histogram at downward convex parts of a frequency distribution of the luminance histogram. The image processing apparatus calculates, for a partial histogram selected from the partial histograms, a difference between a maximum frequency in each of all the partial histograms located on the first side of the selected partial histogram, and a minimum frequency within a luminance range from a luminance level of the maximum frequency to that of a maximum frequency in the selected partial histogram as a drop, and sets a maximum one of the drops calculated for the respective partial histograms as a drop. The image processing apparatus sets a weight, which becomes smaller as this drop is larger, for the selected partial histogram, and calculates a weighted average of the luminance histogram, thereby acquiring a luminance value for the tone correction.

Abstract: A recording apparatus has a controller that controls a conveying roller and a discharge roller for conveying a recording medium. The controller controls the rotation phases of the conveying roller and the discharge roller when the recording medium leaves the conveying roller before the recording medium enters the conveying roller.

Abstract: The present invention provides an optical image acquisition apparatus, while controlling the amount of light within the range prescribed by safety standards, etc., decreasing in image acquisition time by using a simple configuration, as well as securing a high resolution of an optical image by using adaptive optics. Provided is an optical image acquisition apparatus having adaptive optics, the adaptive optics includes: a wavefront aberration detector for detecting a wavefront aberration in a reflected or backscattered beams generated when a plurality of beams are scanned on a surface, and a single wavefront aberration corrector for correcting a wavefront aberration in each of the plurality of beams, based on the wavefront aberration, and the plurality of beams enter the single wavefront aberration corrector with different incident angles and are overlapped on each other, and the wavefront aberration in each of the plurality of beams is corrected.

Abstract: This invention allows focus detection devices to be smoothly and quickly switched even if different image capturing frame counts or image capturing field counts are set in accordance with image capturing purposes. An AF system selection unit switches focus detection methods based on a direct distance measurement AF unit and captured signal AF detection unit in accordance with the frame count or field count of a captured signal.

Abstract: The present invention displays a broadcast program without causing discomfort to the viewer caused by a shift in the display position. The burn-in of the display apparatus when displaying EPG and GUI images is prevented. When viewing a channel, the timing of events such as the broadcast start time of the next program and the insertion of CM video are acquired from program attribute information such as the SI and metadata. Information such as the time of the next program or insertion of an advert is detected from the attribute information, and video data that is displayed in the display area of the display unit is changed at that time. The change in video data is executed when setting the area of the video data to be applied to the effective video data area to the display area, by changing the coordinate data of this area.

Abstract: This invention provides an image forming apparatus capable of preventing image omission caused by registration error correction, a control method therefor, and a program. Error amount information is acquired which is stored in a storage medium and represents the error amount of the scanning line of exposure light in the exposure scanning direction on an image carrier. The image data is modified on the basis of the acquired error amount information. A masked area for restricting the output position of an image visualized on the printing medium is modified on the basis of the modification amount of the modified image data.

Abstract: Upon re-creating a conversion table, which is created for each device and viewing conditions, so as to absorb variations of the color reproduction characteristic of a device, data indicating the relationship between color signals on the color space of the device whose color reproduction characteristic has varied, and color signals on a device-independent color space must be obtained again. Hence, input data is converted into output data using conversion tables for input and output conversions, which are created for an input or output device and for each conversion setting, and a conversion adjustment table. The conversion adjustment table is modified in correspondence with variations of the color reproduction characteristic of the input or output device or color correction for the input or output device.

Abstract: The present invention relates to a radiation image taking apparatus including: a radiation image acquisition portion that acquires an electronic image based on a radiation transmitted through an object and outputs the electronic image; an image taking direction designation portion that designates a posture of the object with respect to the radiation image acquisition portion; a display portion that displays the posture of the object on at least one plane of the radiation image acquisition portion; and a coordinate conversion portion that performs coordinate conversion of the electronic image. The radiation image taking apparatus further includes a control portion that controls the displaying of the posture by the display portion and the coordinate conversion by the coordinate conversion portion based on the posture designated by the image taking direction designation portion.
